FIELD

BACKGROUND

Robotic automation process in building construction is an emerging technology and involves the use of one or more robotic devices that are applied to construct the building or essential components composing the building, such as a floor panel, a wall panel, a door panel, a window panel, or any other components, in a fully automatic or semi-automatic way.

The robotic devices are usually equipped with end effector to mount and connect tools, such as a gripper or a drill, that is used during the constructing process. The robotic devices are pre-programmed with sequences of specific motion commands and commands for other operations in order to cause the robotic devices to complete the constructing process.

The robotic automation construction is suitable for constructing unique and special structures with features of high complexity, high-mix, and low-volume, and is proved with high degrees of versatility, diversity and flexibility to perform construction works. Through the decades of development, currently there are two major robotic automation construction methods available, the on-site robotic construction scheme and the off-site robotic construction scheme.

However, the preparation of numerous parameters, actions, motions and paths of the robotic devices to carry out the constructing process is highly complicated and sophisticated, required to be scheduled, planned, validated, and rehearsed repetitively for many times, prior to the commencement of the constructing process, and impossible to be done by using actual robotic devices.

Hence, there have been proposed quite a few conventional various robot simulators, to duly assist users in performing the preparation. Nevertheless, the issue is, those robot simulators are yet too complicated to learn and use, although they usually provide various graphical user interfaces for users to operate. In order to well manage those simulators, the users are required to be proficient in at least two or more programming languages.

Hence, there is a need to further develop and design a series of assisted visual programming toolbars or panels with for example customizable configurations and are capable of visualizing the arrangement and scheduling processes for a single robot or multiple robotic devices, to solve the above deficiencies/issues.

A computer-assisted cloud based robotic construction software platform 40 (hereinafter referred to as the platform for short), also known as a robot simulator, is established based on the software as a service (SAAS) technology and the platform as a service (PAAS) technology and a backend cross-platform software. The platform 40 is originally installed and functions on the cloud computing server system 50, addressed on the internet by specifying a uniform resource locator (URL), and thus available to users or subscribers over the internet. Any user is able to access, use, and operate the platform 40 easily by connecting to the internet by one's own user device 20, opening the web browser 30 on the user device 20 and entering the URL directing into the web browser 30.

Preferably, the robot or robots are industrial-use multi-axis robots and used in construction process, such as semi-automated construction, automated construction, or near-site construction, to perform a physical fabrication task, in particular, a construction component prefabrication task. The construction process may involve the use of one or more robots that may be used to construct a variety of components of a building. The robots may be equipped with end-effector-mounted tools, such as a gripper or a drill, that may be used during construction process. The actual robots are configured and controlled to act according to the predetermined motion command set including sequences or paths of specific motions sent from the respective controllers to complete the specified task.

The platform 40 is preferably a no-code robotic motion simulation software, and the generated visualization interfaces in the web browser 30 may provide multiple visualization-based functions and various easy-to-use robotic programming tools. The platform 40 provides a simulation to real (sim-to-real) virtual physical environment with built-in physics engine that enables virtual robot objects to simulate or approximate universal forces existing in the real world, such as gravity, velocity, acceleration, friction, etc., for any users with different level of computer skills distributed from ordinary people, such as subscribers or contractors, to professionals, such as programmers, designers or engineers, to simulate robotic motions or paths without writing or typing a single line of code.

The platform is configured to generate a visual programming panel embedded in the visualization interface for any user to program and configure robotic motions performing in the robot simulator graphically and visually. The visual programming panel graphically shows a variety of blocks with different lengths that are sequenced and arranged upon a timeline editor. Each of the variety of blocks represent different predefined robotic motions respectively. By utilizing the visual programming panel, any users are allowed to program and configure robotic motions simply by dragging and dropping the blocks into the timeline editor. The blocks are also referred to as and replaceable by graphical or iconic elements or boxes.

In this embodiment, visualization interfaces are embedded with a variety of quick menus, dropdown menus, buttons and toggles with highly customizable configurations for the specific purpose of easy-to-use. Any user from ordinary people, such as subscribers or contractors, to professionals, can perform the planning and simulations for robotic construction process without typing a single line of code and actually actuating the robots. In particular, the visualization interfaces are especially enhanced and improved in the aspect of visualizing the timeline-related arrangement and scheduling processes for robotic motions of a single robot, or among multiple robots.

FIG. 2 is a schematic diagram illustrating a standard layout of the visualization interface generated by the platform in accordance with the present invention. The platform 40 is configured to generate a series of visualization interfaces 31 to be provided through the web browser 30 for any user to access and operate the platform 40. Four edges, including the left-hand and right-hand sides and the upper and lower parts, of the respective visualization interfaces 31 are preferably arranged and configured to embed with a variety of functional sidebars, toolbars, operating panels, or functional panels. The most and central part within the respective visualization interfaces 31 is configured to provide a main display window 32 virtually showing an animated simulation for the robots and the work cell. In some embodiments, the visual programming panel 400 is preferably a horizontal toolbar and to be positioned for example at the lower part of visualization interface 31.

FIG. 3 is a schematic diagram illustrating an example visual programming panel embedded in the visualization interface according to the present invention. The visual programming panel 400 preferably consists of at least one timeline editor 100 and a bottom bar 200. The at least one timeline editor 100 is identified by a robot ID filled and designated in the robot ID field 101, which is opened for a user to input, and is assigned to program and configure motions for a target robot corresponding to robot ID.

The timeline editor 100 provides a timeline workspace over a horizontal timeline view in the background. The timeline view may contain multiple timescales that are spaced with each other in an equal or variable distance used to indicate a defaulted time interval, for example, 1 second, in this embodiment. The bottom bar 200 provides a plurality of different blocks 201, and a plurality of control buttons including a play button 221, a forward button 223, a backward button 225, and a play speed button 227, for any users to use.

Each of different blocks 201 are labeled with such as a combination of lettered notations and symbols, represent for a specific motion, and refer to a macro that consists of a series of declarations, statements, codes and structured programming that are automatically generated by the system and enable the end effector or the robot to complete a specific motion consisting of multiple basic actions subject to given conditions and parameters. In some embodiments, blocks can be nested within other blocks. Several example blocks 201 are provided in this disclosure.

For instance, the PTP block 203 is the block 201 labeled with PTP and consists of a macro that is automatically generated by the system and enables the end effector of the robot to complete a movement to move from one point to another point subject to all the given conditions and parameters. The Grip block 207 is the block 201 labeled with Grip and consists of a macro that enables the end effector to complete a grip motion to grip a selected member/object with an adequate pressure subject to the given conditions and parameters.

The LIN block 205 is the block 201 labeled with LIN and consists of a macro that enables the end effector to complete a linear movement from one point to another point in a linear trajectory subject to the given conditions and parameters. The Wait block 209 is the block 201 labeled with Wait and consists of a macro that enables the end effector to suspend or stay still in the current position. The Pick & Place block 211 is the block 201 labeled with Pick & Place and consists of a macro that enables the end effector to lift up and transport the griped member, and place it on a selected place. The Nail block is the block 201 labeled with Nail and consists of a macro that enables the end effector to perform a nailing motion.

The specific motion, which the block represents for, is user-definable, customizable and expandable. The present system allows a user to define and configure a new block represents for a user-defined new specific motion by programming a corresponding API. A user may create a new block to complete a specific motion on one's own interest. The length of each of the blocks 201 represents for the runtime of the specific motion, and is adjustable.

The visual programming panel 400 allows a user to code programs and set up configurations required to drive the end effector or the robot in the robot simulator by simply dragging and dropping the blocks into the timeline editor 100, in a fun fashion like the building of a puzzle, instead of writing complex computer codes. The spatial arrangements of blocks on the timeline workspace in the timeline editor 100 is the sequence of specific motions performed in the robot simulator.

In some embodiments, while the scene, and the conditions and parameters are given and set up, and the target robot is designated in the robot ID field 101, a particular block 201 representing for a specific motion, for example, a PTP block 203 representing a point-to-point motion, is selected and dragged into the timeline editor 100. The length of the PTP block 203 is duly adjusted and represents for the runtime or the schedule of the point-to-point motion that is inversely related to the speed of motion. The fixed-interval timescales distributed over the timeline view is capable of assisting in the estimation of the runtime for completing the point-to-point motion.

More and more blocks are allowed to add into the timeline workspace in the timeline editor 100 with a particular sequence to form a chain of motions for the target robot to perform in the robot simulator. In some embodiments, multiple block including the LIN block 205, the Grip block 207, the LIN block 205, the PTP block 203, the LIN block 205, the Grip block 207, and the LIN block 205, are sequentially added into the timeline workspace, as shown in FIG. 3.

In FIG. 3, the horizontal spatial arrangements of the above all blocks in the timeline editor 100 refers to the chain of motions consisting of the point-to-point motion, the linear motion, the grip motion, the linear motion, the point-to-point motion, the linear motion, the grip motion, and the linear motion performed in sequence by the target robot in the robot simulator. The timeline editor 100 demonstrates how a set of robotic motions is sequenced and scheduled over time.

Whenever the arrangements of the blocks are done temporarily or periodically, the play button 221 is clicked to commence the animated simulation of the programmed chain of motions in the main display window in the visualization interface in FIG. 2. The present visual programming panel 400 is helpful to reduce the barrier of entry for novice player or user as they begin learning robotic construction. At the same time, FIG. 2 is also used to illustrate an animated simulation of robotic motions for a single-robot implementation demonstrated in the main display window 32 in the visualization interface 31 according to the configurations defined on the visual programming panel 400 including a single timeline editor in accordance with the present invention.

When the animated simulation shows an acceptable result for the robotic motions, the robot simulator is enabled to conclude the result by transforming the programmed robotic motions defined and configured on the visual programming panel into a motion command set, and stream out the motion command set to the designated actual robot to move accordingly, so as to perform tasks in, for example, an off-site robotic construction.

FIG. 4 is a schematic diagram illustrating an example visual programming panel including dual timeline editors and embedded in the visualization interface according to the present invention. When there are multiple robots required to program and coordinate the robotic motions thereamong, a second timeline editor 300 or more timeline editors are further plugged into the visual programming panel 400 as per user's request. As shown in FIG. 4, which demonstrates a scenario of dual-robot implementation, the first timeline editor 100 is assigned to program motions for a target robot with the robot ID of KR90 1 that is designated in the robot ID field 101 by user, and the second timeline editor 300 is assigned to program motions for a target robot with the robot ID of KR90 2 that is designated in the robot ID field 301 by user.

In some embodiments, whenever the scene, and the conditions and parameters are given and set up, and the arrangements of the blocks for the target robot KR90 1 and the target robot KR90 2 are done temporarily or periodically, the play button 221 is clicked to commence the animated simulation of the programmed chain of motions for a scenario of dual robots in the main display window in the visualization interface in FIG. 11.

FIG. 5 is a schematic diagram illustrating an animated simulation of robotic motions for dual-robot implementation demonstrated in the main display window in the visualization interface according to the configurations defined on the visual programming panel including dual timeline editors in accordance with the present invention. As shown in FIG. 5, an animated simulation of robotic motions for dual-robot implementation demonstrated in the main display window 32 in the visualization interface 31 according to the configurations defined on the visual programming panel 400 including dual timeline editors.

Preferably, the robot simulator may automatically call and execute an intelligent multi-robot motion coordination algorithm component, to autonomously coordinate and generate sequences of motions for multiple robots working together within a single timeframe in the animated simulation. When the animated simulation shows an acceptable result for the multiple robot motions, the robot simulator is enabled to conclude the result by transforming the programmed robotic motions defined and configured on the visual programming panel into a motion command set, and stream out the motion command set to the designated actual robots to move accordingly, so as to perform tasks in, for example, an off-site robotic construction.

FIG. 6 is a schematic diagram illustrating a collision warning on the PTP block during the performance of the point-to-point motion according to the present invention. Preferably, whenever the play button 221 is clicked, the robot simulator may automatically call and execute an intelligent collision auto-avoidance algorithm component, to perform a collision-check process, to detect any possible collision with object or material to find out a collision-free path for the end effector or the robot to follow. If there is any collision occurs in a specific motion, the corresponding block is flagged with flashing red color.

As shown in FIG. 6, once a possible collided motion is detected for the performance of the point-to-point motion by the intelligent collision auto-avoidance algorithm component, a flashing red color is marked at the corresponding PTP block 203 on the visual programming panel 400, to warn the user. The user may select to reset or adjust the work cell or the given conditions and parameters in the robot simulator to remove the possible collision. In alternative, the user may select to re-click the PTP block 203 again. The intelligent collision auto-avoidance algorithm component is to automatically compute a collision-free path, in response to the user's operation.

FIG. 7 is a flow chart illustrating the cloud based computer-implemented for visually programming robotic motions in construction according to the present invention. To sum up, the cloud based computer-implemented method 500 for visually programming robotic motions in construction in accordance with the present invention preferably includes the following steps: causing a visual programming panel including a timeline editor and a plurality of motion blocks enabling a variety of robotic motions to be displayed in a visualization interface provided by a robot simulator shown on a web browser (step 501); selecting from a user, at the visual programming panel, at least one motion block from the plurality of motion blocks and adding the at least one motion block into the timeline editor, via a drag-and-drop, to form a motion configuration (step 503); and according to the motion configuration at the visual programming panel, automatically generating a program capable of commanding an end effector equipped on a target robot in a work cell to perform at least one selected robotic motion from the variety of robotic motions in the robot simulator (step 505).

The contents in section of written descriptions of the invention disclosed in U.S. Provisional Application No. 63/007,060, filed on Apr. 8, 2020, now pending, is fully incorporated by reference as follows.

The present invention relates to a timeline based manually-operated visual panel module used for coordinating and scheduling motions of multiple virtual robots which the visual panel is preferably embedded in a browsable robot simulator platform which provides an animation-based programming interface which allows the user to program the robot motions without learning and typing lines of code.

The visual panel is configured at the top or the bottom in the animation-based programming interface and presented as a programming panel, and consists of a robot identification window and timeline window in principal. The robot identification window is used for showing a name, a symbol or a code for robots, and the timeline window includes multiple large-scale time division slots further including multiple small-scale time division slots. No matter the multiple large-scale time division slots or the multiple small-scale time division slots, each of slots are equally spaced and distributed in the timeline window.

There is a block set consisting of multiple default action blocks, a.k.a.: objects or blocks, such as but not limited to, a PTP block, a LIN block, a Grip block, a Wait block, a Pick & Place block, and etc., shown at the lowest bottom of the panel. Each action blocks typically represent a programming instruction that enables the robot to act a specified action. For example, the Pick & Place block is simply a programming instruction enabling the robot to pick up some thing and place it to a specific spot. Users are allowed to newly establish and define one's own action block that is currently not included in the block set, and put it into the block set.

A user manually selects an action block out of multiple action blocks from the block set, and attach it to the timeline window. The selected action block is horizontally enlargeable or expandable, such that the user is allowed to freely adjust the width of the action block to render its left edge aligned with a starting time of the action and its right edge aligned with an ending time of the action respectively. The user can put more action blocks into the timeline window to schedule and arrange a chain of motion consisting of a series of actions the virtual robot performs. When multiple blocks are continuously place and shown in the timeline window, a motion bar representing the chain of motion is thus formed, and instructing the robot to act accordingly.

Users are allowed to add more virtual robots into the robot identification window and attach multiple action blocks into the timeline window for the added virtual robot. When there are multiple virtual robots are put into and presented in the visual panel, one not skilled in programming still can synchronize, arrange, schedule, coordinate and timely aligned the actions and the sequence of actions among robots easily and simply, just by adjusting the sequences, arrangements and sizes of the multiple blocks manually and intuitively.

Further to the above, the method and module includes features as follows: reducing the learning threshold of robot programming, for which most engineers can learn and control the basic robot operations within one hour.

Further to the above, the method and module includes features as follows: linking building information model to robot controls, off-site manufacturing, on-site facilitation, and building beyond the human workers, etc. A design tool set that ties the BIM design to the robotic prefabrication.
